Hello Adam,

 

today we have done some other tests and could fix the problem by ourselfs. The reason for the MessageBox "Upload is unable to find the uploaded file in Temp-Directory ...", was that the C:\Windows\Temp\AjaxUploaderTemp potentially have some wrong rights. I delete this directory and during the next upload the AjaxUploaded creates this directory new, but with the right user rights settings, so that an upload was possible.

 

Thank a lot so far. I hope there are no other problems in the future.

 

Regards,
